Top Research Papers on Hair Growth

Patients with no dietary restrictions, but with major consideration of the life adjustments, did better over a three-year follow-up period than a similar group treated by traditional methods including dietary restriction.

A trichogram from the parietal region showed a decreased anagen to telogen ratio of 22/78 (against 90/10 in normal condition) with all hair presenting tapered tips rather than cut ends, indicating that hair had never been cut.

Hair follicles sustain repeated cycles of hair loss and regrowth and stem cells are responsible for driving this cycle of growth and can repopulate follicles and surrounding.

The anagen:telogen ratio is the best indicator for cycle status given the impracticalities of measuring the duration of anagen, and all methods have their special application range and advantages.

It is confirmed that there will be no further action on the basis of nationality or ethnic origin.

In this chapter, structural and biologic characteristics of hair follicles in different body regions are reviewed and regulatory factors influencing both normal and abnormal hair growth are discussed, with emphasis on androgenic action associated with both hirsutism and androgensic alopecia.

Cynatine®, HNS has demonstrated that it can improve the strength and appearance of hair as well as reduce hair loss associated with washing, and the ability of Cynatine® HNS to protect the skin from oxidative stress has been determined through a combination of in vitro and in vivo measurement.

This review will consider the various techniques of growth measurement: duration of the growth-cycle, kinetic studies of the hair root, length and diameter measurements including autoradiography, compound measurements—the Trichogram, and 'pluckability' as this technique has been suggested as an easy cheap measurement of malnutrition which can be performed in the 'field'.

This book approaches the biology of hair from many different directions, and ranges over embryology, anatomy, histochemistry (including electron microscopy), the details of mitotic activity in the hair follicle, the chemistry of keratinization, the problem of hair pigment, the skin, its vascularity and their relationship to hair growth, nutritional factors, hormonal factors, age.

The often-devastating impact of female hair loss requires dermatologists to diagnose and quell underlying pathology as quickly as possible, usually using combination therapies followed by long-term maintenance.

Real-time imaging in vivo reveals cellular mechanisms of hair growth and provides new insights into how follicle establishment and turnover are regulated by the immune system.

Hair growth devices (20, 20A, 20B, 20C, 20D, 20E, 20F), with which growth of body hair is promoted, comprise a light source part (3) for generating light (H) having the specific absorption wavelength of water of 950 nm or 1450 nm, and a light guide part (4) for guiding the light (H) generated by the light source part (3) to the skin.

The present method can be used for either accelerator or inhibition of hair growth or hair dense in a subject.

The invention features methods of promoting hair growth in a subject by inducing or mimicking the effects of Wnt promoted signal transduction, e.g., by increasing the level ofWnt protein or administering an agent which mimics an effect of WNT promoted signalTransduction.

The invention discloses a hair growth device. The hair growth device includes a first light irradiator configured to irradiate an invisible light of invisible wavelength range, for hair growth; and a second light irradiator configured to irradiate a visible light of visible wavelength range. The second light irradiator is configured to direct the visible light to either inside of a light irradiation area of the light from the first light irradiator or outer circumference of the light irradiation area.

Treatment of excess hair growth represents a challenge for dermatologists and endocrinologists after combination of topical, systemic, light assisted treatment options and lifestyle modification.

The hair follicle is one of a few human tissues containing stem cells that are interspersed within the basal layer of the outer root sheath and in an area called the bulge and from this reservoir stem cells migrate to hair matrix and start to divide and differentiate.

A cosmetic method for reducing the growth of androgen-stimulated hair in mammals by induction or activation of a UDP-glucuronosyltransferase or a sulfotransferase, wherein the compound is present in the composition in an amount effective to reduce hair growth is selected.

Long comprising intact, sexually mature male hair growth of androgen stimulation of hair growth in humans, including rate characteristics and can be suppressed by topical pharmaceutically active ornithine decarboxylase dermatological carrier substance.

The composition exhibits excellent hair loss prevention and hair growth promoting effects when the composition further comprises an inhibitor of 5alpha-reductase activity and an activator of hair follicle cells, it exhibits better hair loss Prevention and hairgrowth promoting effects.
